Performance Prediction of Low Temperature Air-Cooling Extended Surface by Several Comparative Methods

Abstract

In a paper by one of the authors some time ago on fin heat transfer¹, use was made of the geometrical electrical analogy in studying temperature patterns of extended surface, particularly those located internally within the element structures» One of the fins studied was of thin section, shown in Figure 1; its length beyond the primary surface was twenty times its own thickness, such as might be found with a metallic fin as often used in low temperature air heat transfer equipment.
